This invention relates to control means for earth pulverizing machines. 7 I

An object of my invention is the provision ofsimple and efficient means for adjusting the pulverizing rollers of the machine.

Another object of the invention. is: the I provision of simple and eificient means for adjusting the height of- -the seeding means. :A still further'object of theinvention is the construction of asimple and efficient hub for the primary tractor wheels of the machine.

Another "object of my invention is to simplify the machine shown in my prior 1 Patent No. 1,045,295, issued Nov. 26, 1912. With the foregoing and otherobjects in view, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully '20 described, illustrated inthe accompanying drawings, and more particularly pointed out in the appended claims. x g

A suitable king bolt 16 extends throughplates 14 and c 1 15 and axle 6, as well astongue structure 17. The tongue structure, 1'] {(Fig. 3)., may pivot slightly upwardly at 18', so that thejar will not to be so great on the draft animals, wherebymy machineis easier on thedraft animals than if a solidor single piece tongue v i V .Ipreferablyemploy two pulverizing rollers 19; these rollers are specifically described in my co p'ending application Serial No. 590,953, filed February 4, 1932. To ver- 1 j use at both ends bearingdevices 20, as fully illustrated in Fig. 4. Each bearing device comprises abracket 21 secured tothe frame 1. Two vertical rods 22, extend at their upper ends through bracket 21.. 'Aplate 23 is fastened by lock bolts 24 onthe lower end of rods 22. -Plate 23 is provided withoutwardly extending -lug s]25.- On each lug 25 is mounted pulley 26., Over pulleys 26 travels' cable 27 This cable 27 is, securely fastened at. 28 (Fig. 2) to frame 1 with its outer end wound around. drum 29. Drum 29 is provided with a suitable" ratchet "30' engaged by pawl 31, whereby the bearing devices can be manually adjusted to controlv the depth P NT OFFICE ta I each end of the axle.

.the other. A plate is also on the axle 33 (Fig. 4). Hoisting cable 36 is connected atits lower end to platev 35; the opposite end ofcable36 is wound around drum 37 this drum is fixedly secured to two part shaft 38," so that when shaft 38'is rotated, the bearing devicewillj'be raised or lowered, depending 20 upon the, direction of rotation-of the shaft.

Shaft 38 is journ'alle'd upon standards 39 mounted upon frame 1. ,Two' sprocket wheels 40 are used in constructing'my mechanism, one on the outer end of each section of the shaft 38. Around each sprocket wheel 40 passes chain 41'; chain 41 is also mounted upon sprocket wheel42; sprocket wheel 42 is rotated through main shaft 4 and the master wheels 5. 4 Clutch device 43 is provided-on each section of shaft 38 and is operated through the medium of cable 44 connected to one of the several lever devices 45; these lever devices are positioned upon standard 46 contiguous to seat 12. By means of the clutches 43, the shaft 38 can be operated at the willof the operatontoraise or lower the pulverizing rollers 19 when clesired. Also onthe outer end of each section of shaft 38 (constituting a two-piece single shaft, across the machine) is positioned sprocket wheel'47 around sprocket wheel 47 travels chain 48. This chain 48 passes around sprocket 49 (Fig. 1); sprocket 49 is secured to shaft or axle 23 of the pulverizing roller 19,-whereby the pulverizing roller is rotated inone directionwhen the machine is drawn forward over the ground, butby means. of ratchet 50, when the machine is backed, the sprocket wheels 47. will be thrown out of mesh and the pulverizing rol ers'will be inoperative. For keeping each sprocket chain taut, I provide a chain tightening device 51, which comprises toothed wheel. 52 mountedupon pivoted bar 53 (Fig. 1), which bar, through the action of spring 54 holds the toothed wheel 52ftightly against the chain 48. When the bearing devices 20 a reraised suiiicientlyto lift the pulverizing rollers from contact with the ground, the chain tightening devices 51 will still keep the chains relatively taut, but will yield readily when the pulverizing rollers are loweredincontact with the ground, for operating purposes. 1 p

There are a sufiicient numberof the lever devices 45 to accommodate the necessary VA drum: 56-is-fixedly secured to each lever device 45 as ,a' part thereof, whereby the lever; device operates the. drum to wind its cable thereon sufficiently for operating the unit to which ai'cable is connected. An ordinary locking plate 57, fixedly secured to shaft 55 isprovided for each'lever device to hold the same in a manually adjusted position. a I 7 I have found in actual practice that it is very desirable to brace frame 1 near its center, and consequently, I have invented a bracing frame-device 58 comprising an upstanding auxiliary frame 59 having angu-' lar ends 60 secured upon the sides of frame 1 (Fig; 11). A horizontal bracing rod 61 extends across frame 59 and connects the sides. Braces 62 are connected at their upper ends to'the central part of the auxiliary frame'59 and at'th'eirouter ends are connected t'o'the sides of said frame 59 near its angle ends 60. A vertical central rod 63 has a hook 64 on its lower end which fits over part of thecentralj brace 2.- The upper end'of'rod 63 is passed through the top of frame 59 and bymeans of nut 54, the 'rod 63 is held tightly in position.

Two covering rollers- 65 are provided to assist in covering the seed that isplanted through the medium of the planterfat'tachment 66. "Thisplanter attachment comprises seed box 67*prov ided' with a suitable number'of chutes 68. A shaft 69- extends through the chute 68 and operatessuitable seed discharging means "of the seed box 67.

This shaft 69 (Fig:'2) is; drivenby means ofsprocket chain 70' which passes over a suitable sprocketwheel 71, on shaft69, and a suitablesprocket wheel -72 on main shaft 2., By means of a clutch device 73, operated through -cablef74,"connected to one of the lever devices 45, the operator'can throw in and out of mesh the clutch for controlling the discharge of seed from the seed box 67. On each chute 68 is placed a rubber hose 7 5 (Fig. 6). This hose'extends into seed tube 76. Seed tube 7 6 is provided with a rearwardly extending lug'77, which lug is pivotally mounted at 78 on arm '79." Arm 79 is pivotally mounted at 80 upon depending bracket 81; bracket81 is suitably secured to the frame 1.; *A lug'82 is on arm 79 to which is connected at one end a spring 83, and the other end of thefspring'is connected to lug 84 on seed tube 76, whereby the seed tube is normally held' 'in "an operating position against Web85 of arm 79, but when the lower end of seed tube strikes a foreign object such as a stone, it will kick back to the dotted position A, or further, to allow the seed tube to pass over the 0bstruction Without injury thereto, spring 83 returning the seed tube to its opposite position, as soon as the tube is relieved of its normal strain. Connected to lug 66, fast ened to web 85, is lifting cable 87 This cable 87 is attached to a crank shaft 88; there are two cranks shafts 88 (Fig. 2) each provided with a suitable lever device 89,

-whereby the operator can raise or lower the seed tube adjusting devices when desired.

The hub device 90 (Figs. 7 and 8) of each master wheel 5 comprises an inner conical sectlon 91, which is provided with a plurality of longitudinally ribs 92. A hub section 93 is placed over conical section 91 with ribs 92 fitting therein. A spoke unit 94 is fastened by key 95 upon axle 1 contiguous to the conical section 91 and hub section 93. The spoke unit 94 is provided with large lugs 96 at opposite sides thereof, which are fitted in cut-out portions of notches 97 of the hub section 93. Sprocket wheel 42 is fitted tightly onhub section 93 against annular flange or shoulder 98. A collar 99 is fitted on axle 4 tightly against the hub section 93. By means of this novel construction, a very powerful hub structure is produced which also greatly increases the life of the mechanism.

Referring to the bearing devices 20, and particularly to Fig. 4, on the rods 22, I place a bearing plate 100 against the bearmg 34. On rods 22, against bracket 21, I place one or-more detachable filler blocks 101. This loose block 101 is only in place when the machine is in operation in the field. Against filler block 101 is hearing plate 102. On rods 22 are coil springs 103. These springs 103 bear at their ends against plates 100 and 102. By this structure, the pulverizing rollers are yieldably held against the ground, but the pressure exerted by springs 103 are admirably sufficient for permitting said rollers to perform excellent results.

Inasmuch as the general principle of several of the units of the present mechanism is disclosed in my prior Patent No. 1,045,295, reference may be had to said patent for a fuller understanding of this art, but the improvements disclosed in the'present case make my old mechanism obsolete; While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or 2. In a mechanism of the'class described, i

the combination .with a frame, of a plurality of bearing devices on said frame, each bearing device comprising a bracket attached to said frame, rods extending through said bracket, a bearing slidably mounted on said rods, a bearing plate engaging said rods and said bearing, coil springs around said rod and pressing at their lower ends against said bearing plate, a second plate on said rods and againstthevupper ends of said,

coil springs, filler blocks on said rods between said bracket and said last mentioned plate, and an axle journalled in said bear- 3.
